And We have set none but angels as guardians of the Fire, and We have fixed their number (19) only as a trial for the disbelievers, in order that the people of the Scripture (Jews and Christians) may arrive at a certainty [that this Quran is the truth as it agrees with their Books i.e. their number (19) is written in the Taurat (Torah) and the Injeel (Gospel)] and the believers may increase in Faith (as this Quran is the truth) and that no doubts may be left for the people of the Scripture and the believers, and that those in whose hearts is a disease (of hypocrisy) and the disbelievers may say: "What Allah intends by this (curious) example?"
Kami pun tidak menjadikan jumlah penjaga neraka sebanyak sembilan belas malaikat melainkan untuk menguji orang-orang kafir, agar orang-orang yang diberi al-Kitab meyakini bahwa apa yang dikatakan al-Qur'ân mengenai penjaga neraka jahanam adalah benar dari sisi Allah sebagaimana terdapat dalam kitab-kitab suci mereka. Demikian juga, agar para pengikut Muhammad semakin bertambah imannya, dan mereka yang telah diberikan al-Kitab beserta orang-orang Mukmin tidak lagi meragukan kebenaran hal ini.
